Yes, it does. I just installed it. One small caveat is that the plug that goes to the iMac does not fit through the ring that holds the lock. This is really a minor issue which does not affect the overall use of the unit. The design is excellent, the mount still allows the display to swivel easily, overall a great design.

It says it allows swivel, which is probably the monitor itself up and down. But does anyone know if the stand turns like lazy susan style, and allow turning the monitor left and right? from the base, to face one way or the other.
